Abstract

How do managers, in their role as decision makers, design and implement systems for management of quality? Proposes that there is no one, definitive answer to this question, given various industrial environments and their operating constraints, diverse market conditions and numerous management philosophies. Attempts to address quality management issues in the business‐to‐business industrial service industry by presenting a case study on the quality management approach taken by Diamond Offshore Drilling, Inc. ‐ one of the largest offshore oil‐drilling companies in the world. States that the business‐to‐business industrial service markets are characterized by the sale of industrial services to business customers, who often then use these services to produce goods or services for consumers or other businesses. A wide variety of services are provided by the companies operating in this industry, such as offshore oil‐drilling and exploration, warehousing and public utilities. The case study follows the backdrop, initiation and complete implementation of Diamond Offshore’s Global Excellence in Management Systems (GEMS) programme. GEMS can be characterized as a system deeply rooted in the basics of quality management ‐ customer‐defined requirements and quality through customer satisfaction. Also discusses post‐implementation customer feedback results to illustrate the success of the programme. Based on the GEMS framework and relevant literature, proposes a generalized framework for implementing quality management in firms operating in business‐to‐business industrial service markets.

Abstract

Describes how a group of organizations (consultants, companies and universities) in Houston, Texas, USA created an informal yet organized forum for sharing information, case studies, tools, and methodologies in the area of business process re‐engineering (BPR) to learn from one another’s experiences and to avoid pitfalls in their BPR endeavours. The forum is named “Houston Business Process Re‐engineering Share Group”. Acts as a road‐map for practitioners and academicians who want to establish similar share groups to increase interaction and improve their understanding of principles and methodologies of BPR. Within 40 months of its startup with 24 members, the Houston BPR Share Group membership increased to over 200 ‐ an indication of its utility and the benefits to the participating organizations.

Abstract

Purpose

The two-tank level control system is one of the real-world's second-order system (SOS) widely used as the process control in industries. It is normally operated under the Proportional integral and derivative (PID) feedback control loop. The conventional PID controller performance degrades significantly in the existence of modeling uncertainty, faults and process disturbances. To overcome these limitations, the paper suggests an interval type-2 fuzzy logic based Tilt-Integral-Derivative Controller (IT2TID) which is modified structure of PID controller.

Design/methodology/approach

In this paper, an optimization IT2TID controller design for the conical, noninteracting level control system is presented. Regarding to modern optimization context, the flower pollination algorithm (FPA), among the most coherent population-based metaheuristic optimization techniques is applied to search for the appropriate IT2FTID's and IT2FPID's parameters. The proposed FPA-based IT2FTID/IT2FPID design framework is considered as the constrained optimization problem. System responses obtained by the IT2FTID controller designed by the FPA will be differentiated with those acquired by the IT2FPID controller also designed by the FPA.

Findings

As the results, it was found that the IT2FTID can provide the very satisfactory tracking and regulating responses of the conical two-tank noninteracting level control system superior as compared to IT2FPID significantly under the actuator and system component faults. Additionally, statistical Z-test carried out for both the controllers and an effectiveness of the proposed IT2FTID controller is proven as compared to IT2FPID and existing passive fault tolerant controller in recent literature.

Originality/value

Application of new metaheuristic algorithm to optimize interval type-2 fractional order TID controller for nonlinear level control system with two type of faults. Also, proposed method will compare with other method and statistical analysis will be presented.

Abstract

Purpose

The business enterprises are increasingly focusing on buying and supplying of products and services in a manner to reduce the adverse impacts on the environment, society, and economy. In view of the above, the concept of sustainable supply chain management (SSCM) has received attention of the industry and academia due to its importance on environmental, social and corporate responsibility through economic performance. The paper aims to discuss these issues.

Design/methodology/approach

The structured literature review attempts to map the various theories in the SSCM literature from the perspectives of economic performance, environmental dimensions, and social values and ethics.

Findings

As supply management is vital for enhancing organizational competitiveness, the present work attempts to investigate the theoretical perspectives in SSCM to develop an understanding of the current research activities and future potentials.

Practical implications

This work aims to gain a number of valid insights for the practitioners and the researchers. It also focuses on the perspectives of governance mechanisms for successful implementation SSCM practices in the business enterprises.

Originality/value

As the theory building initiatives with implications on the conceptualization of SSCM is limited in literature, this work has also been able to identify the trends and relevant research gaps to define the potential areas for future research.

Abstract

Purpose

The purpose of this study is to assess the lean performance of a tyre manufacturing firm in India. The key objective is to find key strategic and operational decision‐making dimensions for developing effective lean manufacturing environment in a tyre manufacturing organization.

Design/methodology/approach

This research is empirical in nature where the opinions of a group of experts of an Indian tyre manufacturing firm were consulted to formulate an interpretive structural model (ISM) of the critical success factors of lean manufacturing implementation in a tyre manufacturing organization. The authors have developed an Excel‐based template for quantitative assessment of lean performance indicators on the basis of feedback from the operational staff.

Findings

This research work suggests that financial capability of an organization drives the top‐management commitment for incorporating lean manufacturing practices in a tyre manufacturing organization. Organizational culture and human resource management are the important enablers for developing change management paradigm, which in turn leads to performance improvement. This study also reveals that over‐processing as well as excessive defects are the most detrimental wastes in radial tyre manufacturing, which accounts for high manufacturing cost of radial tyre manufacturing in India.

Research limitations/implications

Since this study is carried out in a single (case) organization, a relatively small sample size restricts the outcome from being considered for generic industrial application. This study none the less is useful for practicing managers and academicians for the development of lean manufacturing strategy in context with the tyre industry since it encompasses insightful views of experienced lower to upper middle level managers.

Originality/value

This paper provides some key enablers for the successful implementation of lean tools in Indian tyre manufacturing, where lean practices are still in the early stage and little literature is available in this context with tyre manufacturing. Also an attempt has been made to develop a simple Excel‐based template for lean assessment in the tyre industry. This template can be used in other industries by simply modifying the key attributes.

Abstract

Purpose

This case seeks to illustrate the specific problem of excessive defects in radial tyres produced in a renowned tyre manufacturing company in India. This paper aims to show how lean Six‐Sigma methodology can be used to tackle the specific issues like defects reduction.

Design/methodology/approach

The management took this problem on top priority as it is eroding their brand value and financial performance. A Mumbai‐based lean Six‐Sigma consulting group was approached to tackle the issue. One of the authors, who is pursuing research on determinants of successful lean manufacturing implementation in Indian industries, joined this project as a part of his field study and he spent considerable time in discussing and observing the issue with people of different hierarchical levels of the company. Lean Six‐Sigma methodologies were incorporated and the problem was evaluated with root‐cause analysis. This case is formulated on the basis of the initial findings of the study in an Indian tyre manufacturing organisation keeping the actual name of the company in disguise.

Findings

On the basis root‐cause analysis of the radial tyre manufacturing process, it was found that presence of foreign particles in the manufacturing environment, under‐ageing and over‐ageing of tyre components, and inefficient bead winding process, were the main culprits of defects. It was confirmed that lean Six‐Sigma methodology can serve as a major tool to reduce defects in the tyre manufacturing process in India.

Originality/value

This paper provides some key insights to the successful adoption of lean Six‐Sigma tools in an Indian industrial environment, where lean practices are still in the very nascent stage and very little literature is available in this context.

Abstract

E‐marketplaces are one of the relatively new trends that are affecting buyer‐supplier relationships. Although there have been several failures in the e‐business arena, whether it is business‐to‐business (B2B) or business‐to‐consumer (B2C) e‐commerce, there is no doubt that the Internet has changed the way that business is done in several ways. It has been shown that electronic commerce can fundamentally change the inter‐organizational processes involving buyer‐supplier relationships. It reshapes these buyer‐supplier relationships, improves a business's core processes, and helps reach new markets or segments through the electronic medium. This paper discusses the opportunities and challenges facing e‐marketplaces today, and also the concerns facing potential participants in these e‐marketplaces who are trying to weigh the risks presented by such participation and the possible benefits that can be reaped by streamlining supply chain processes. Some of the major concerns facing existing and potential buyers and suppliers that are discussed in this paper include integration issues, security issues and antitrust issues.

Abstract

Purpose

The purpose of this paper is to examine the impact of the future of trading on volatility as well as the efficiency of the stock market of BRIC (Brazil, Russia, India and China) countries. This study also investigates the presence of day‐of‐the‐week effect in BRIC countries' stock market.

Design/methodology/approach

This study uses closing prices of IBrx‐50 for Brazil, RTSI for Russia, Nifty for India and CSI300 for China to represent the stock market of BRIC countries. The Run and ACF tests are used to see impact on market efficiency. GARCH M model is used to see the impact on volatility and day‐of‐the week effect.

Findings

The insignificant coefficient of variance in the conditional mean equation of GARCH M implies that the market doesn't provide higher returns during the high volatility period. The results of the Run test showed that the Russian stock market became efficient after introduction of future trading. However, ACF showed no effect of introduction of future trading on autoregressiveness of stock returns. The result of GARCH M indicates that future trading led to reduction in the volatility of the Indian stock market. There are some evidences of presence of day‐of‐the‐week effect in the Indian stock market.

Practical implications

This paper will help regulators to form appropriate policies as the market would have to pay a certain price, such as loss of market efficiency, for the sake of market stabilization. This will also help investors to make investment decisions, especially investing in these indices as the existence of the significant day‐of‐the‐week effect and the inefficiency in the stock market would be very useful for developing investment strategies.

Originality/value

This paper will be useful for both investors and regulators in decision making.

Abstract

Purpose

The purpose of this paper is to examine the extent to which Indian consumers of different demographic groups vary in terms of shopping mall visits (frequency of visit, hours spent in the mall, and number of shops visited) and purchase behaviour (total money spent, number of shops purchased from and number of items purchased).

Design/methodology/approach

The study used a self-administered survey of 400 Indian mall shoppers to examine Indian shoppers’ behaviour with respect to visiting and buying behaviour. Descriptive analyses and χ2 tests were conducted to identify patterns and capture the significant relationships in shopping behaviour across different demographic segments.

Findings

The results show that shoppers of different age cohorts and from different household sizes behave differently from one another in a significant manner. In terms of gender, however, men and women tend to behave in a similar manner in terms of visit frequency, time and money spent per visit. The study also provides insight into where the differences occur and between which specific groups.

Research limitations/implications

Data comes from one major city of India which limits the generalizability of the results.

Practical implications

For mall managers and retailers, the study findings indicate that the stores that serve recreational needs should focus more on younger segments, where men and women share similar buying patterns. Findings from this study could also be used for segmentation exercises and to build strategies to convert footfall into actual purchase, especially within the rapidly growing Indian mall market.

Originality/value

The study adds value to the body of retail literature and provides empirical evidence from the rapidly developing Indian market. The study also provides insight into where differences occur and between which specific groups. By highlighting the differences in greater detail, the study benefits retailers in general and specifically, mall managers.

Abstract

Purpose

The chapter explores how gender has been an integral part of the nation building project in post-liberalisation Hindi cinema, popularly, known as Bollywood.

Design/methodology/approach

This chapter is based on primary data gathered through interviews with prominent members of the Hindi film industry along with a detailed content analysis of commercially successful post-liberalisation mainstream Hindi films.

Findings

It highlights how the representation of gender has been a central axis around which the tension between tradition and modernity has been played out in Hindi Cinema. The construction of Indianness post-liberalisation has questioned gender politics but proposed easy resolutions which fit into the larger nationalist narrative. In doing so, it has used the diaspora as a category to produce a nationalist account which is simultaneously essentialised and transnational in the quest for projecting India’s aspirations on the global platform.

Originality/value

The chapter provides important insights into the role of popular Hindi cinema, often brushed off as frivolous, in contributing to the mainstream discourse on nationalism post-liberalisation.
